    * without hyperfine interaction
    E = g*muB*B0*mJ
    mJ=1/2: E = -muB
    mJ=-1/2: E = muB
    mJ=-3/2: E = 3muB

    So:
    mJ=-1/2 –> 1/2: delta(E) = 2muB
    mJ=-3/2 –> -1/2: delta(E) = 2muB

    * with hyperfine interaction (Bhf = 10T)
    A*mI*mJ = g*muN*Bhf/J *mI*mJ = 20/3 * muN * mI*mJ
    with mI = +/-1/2
    So:
    mJ=-1/2 –> 1/2: energy levels split in two:
    From (10/3+5/3)muN –> (-10/3-5/3)muN: delta(E) = 10muN
    From (10/3-5/3)muN –> (-10/3+5/3)muN: delta(E) = 10/3*muN

    mJ=-3/2 –> 1/2: energy levels split in two:
    From (-10+5)muN –> (-10/3+5/3)muN: delta(E) = 10/3 muN
    From (-10-5)muN –> (-10/3-5/3)muN: delta(E) = 10*muN
